There are currently 2 maps on Days of Darkness.
The map Carentan has only one flag.
It's a very close quarters map and is not recommended to go with the Sniper (unless you want to).
It's a very similar to the Call of Duty map Nuketown.
Omaha Beach Edit
The map Omaha Beach has three flags.
This is a very large map, with the Allies spawn being the beach and the Axis spawn in a forest. The Axis members can get cover in bunkers and Allies in boats and hedgehogs.
Allies must teamwork all times, mainly if there are Axis soldiers in bunkers with MGs/sniper rifles.
